Review WILWOOD Radial Mount Caliper Piston Bores And 1.88 /1.62

The Wilwood 120-13285-RD Aero4 Radial Mount Caliper is a high-performance brake component engineered for applications that demand superior stopping power and responsiveness. This caliper features radial mounting, which allows the pistons to move in a straight line to the rotor, providing better brake modulation and more even pad wear.

The Aero4 caliper is available with piston bores measuring 1.88 inches and 1.62 inches. The larger 1.88-inch bore size is suitable for larger brake pads and provides increased clamping force for more aggressive driving styles. Conversely, the smaller 1.62-inch bore size is designed for smaller brake pads and is often used in applications where minimal unsprung weight is desired.

The Wilwood Aero4 caliper is manufactured using advanced aerospace techniques, ensuring a lightweight yet robust design. The caliper housing is made of forged aluminum, which provides excellent strength and durability while minimizing unsprung weight. The caliper also features adjustable brake pads, allowing for fine-tuning of the brake pedal feel and ensuring consistent braking performance over the life of the pads.

The Aero4 caliper is designed to work with a variety of rotor sizes and is available in both left-hand and right-hand configurations. It is also compatible with a wide range of brake pad compounds, allowing you to choose the best option for your specific application.

In summary, the Wilwood 120-13285-RD Aero4 Radial Mount Caliper with piston bores measuring 1.88 inches and 1.62 inches is a high-performance brake component that delivers superior stopping power, responsiveness, and adjustability. Its radial mounting design provides better brake modulation and more even pad wear, while its lightweight forged aluminum construction ensures excellent strength and durability. The Aero4 caliper is suitable for a wide range of applications and is available in both left-hand and right-hand configurations.

Pros and Cons of Buying Wilwood Aero4 Radial Mount Caliper Piston Bores (120-13285-rd, 1.88 / 1.62)

The Wilwood Aero4 Radial Mount Caliper Piston Bores (120-13285-rd, 1.88 / 1.62) are a popular upgrade for high-performance brake systems. These piston bores offer improved braking performance and are suitable for various applications. In this analysis, we will discuss the advantages and disadvantages of buying these Wilwood brake components.

1. Enhanced Braking Performance: These piston bores are designed to provide superior braking power and response. They are engineered to minimize heat generation and expand consistently during heavy braking, ensuring better stopping power and reduced brake fade.

2. Adjustable Clearance: The adjustable clearance feature allows fine-tuning of the piston-to-drum or disc clearance, ensuring proper pad-to-rotor contact for optimal braking performance and longer pad life.

3. Radial Mount Design: The radial mount design offers increased stiffness and better force transmission between the caliper and the brake rotor, leading to improved braking consistency and feedback.

4. Compatibility: These piston bores are compatible with a wide range of Wilwood calipers and various brake applications, making them a versatile choice for various vehicle types and configurations.

1. Cost: The Wilwood Aero4 Radial Mount Caliper Piston Bores are more expensive compared to OEM piston bores. Upgrading to these high-performance components may require a significant investment for some users.

2. Installation Complexity: Installing these piston bores may require advanced technical skills and experience, especially for those with no prior experience in brake system upgrades.

3. Potential for Uneven Brake Pedal Feedback: Depending on the installation and calibration, some users might experience uneven brake pedal feedback with these high-performance piston bores. Proper calibration and bedding-in of the brake pads can help mitigate this issue.

The Wilwood Aero4 Radial Mount Caliper Piston Bores (120-13285-rd, 1.88 / 1.62) offer significant advantages in terms of enhanced braking performance, adjustable clearance, radial mount design, and compatibility. However, their higher cost, installation complexity, and potential for uneven brake pedal feedback may deter some users.

If you are looking for improved braking performance, these piston bores are an excellent choice. However, it's essential to weigh the advantages against the potential downsides, considering your technical skills, budget, and requirements. If you're unsure about the installation process, consider seeking professional assistance to ensure a proper installation and optimal performance.
